    Don't understand this

    Code:
    (a) Is/Are there error(s) with the following class definition and/or object creation? If no, provide code to create ONE object. If yes, please provide your explanation for credit.
    
    
    #include <iostream> 
    using namespace std; 
    // For all classes, the negativity of the fraction will apply
     // to the numerator
    class FractionA { 
    public:
    int n;
    int d;
    }; 
    
    int main( void ) {
    
    FractionA frA; // Line 1 : POSSIBLE CODE TO CREATE OBJECT 
    
    return 0;
    }
    What does it mean by "Provide code to create ONE object?"
    Thanks.

    You've created the object successfully. What else do you need?
    Yes, class will be created without any errors. In main, you've successfully created the object as it'll call compiler default constructor.

    Yes, but the question asks if there isn't any errors in the provided code (This code was already given) then I should fill in code to create an object. Is there an object already?

    I think you should read classes first.
    Yes, there is an object in your main(). Try to figure that out. I gave you a clear hint. Not only hint but the exact thing :-)

    Oh sorry, I didn't realize that... Yes, frA is an object but why is it asking me to create an object if there already is one?

    So, create one more if you want to and if it's desired by the user. :-)

    Yes, I can do that, but the question specifically says "one object". I think this is just a mistake by my instructor. Thanks for your help.
